Buffer, have you contacted Canadianpond.ca yet, if not touch base with Mario. I would consider a windmill that will produce the highest amount of cfm available.Place a pair of high volume air stations in 10-15 ft of water even if you have to suspend them This will allow the system to operate at 5-7.5 psi which will only take approx 10 mph wind to start pumping.This may allow enough oxygen if and when your water is at a critical state.
